WILHELM H. WILHELMY, OF

NEBRASKA CITY, NEBRASKA.

HYDROCARBON-BURNER;

No. 868,955. Specification of Application filed March 26,

To all whom it may concern:

Be it known that I, WILHELM H. WILHiiLMY, a citizen of the United States, residing at Nebraska City, in the county of Otoe and State of Nebraska, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

My invention relates to improvements in hydrocarbon burners designed with special reference for use in connection with cooking and heating-stoves. Furthermore, an attachment is provided for transforming the device into a crude oil burner for use in such stoves.

The primary object of the invention is to provide a generally-improved device of this class which will be exceedingly simple in construction, cheap of manufacture, eflicient in use, and much better adapted to its intended purposes than any other device of the same class with which I am acquainted.

Another object is to provide a burner of this class which may be readily attached to or detached from any ordinary cooking-stove, the present embodiment being attached to a central bed-plate corresponding in its outer outline or contour to the central plate of an ordinary cooking-stove, the gas-generating-pipe or vaporizing retort portion being suspended within the fire-box and by regulating the drafts, by means of the ordinary damper attachments of the stove, the proper amount of air admitted to the mixer to mingle with the vapor at the point of combustion, thereby creating an intense clear white heat and reducing the formation of soot and dirt to a minimum. With these and other ends in view, the invention consists in the novel construction, arrangement and combination of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure 1, is a top plan view of my invention. Fig. 2, a cross-sectional view taken through line 2,-2, of Fig. 1. Fig. 3, a detail view, partly in section, of a crude-oil attachment. Fig. 4, a horizontal sectional view taken through line 4,4, of Fig. 2, the ends of the generating-pipe and oil-burning-pan being broken away. 7

Similar characters of reference designate like parts throughout all the figures of the drawings.

The improved burner, in the present instance, is mounted upon a supporting-plate 1, corresponding in its outer contour or outline to the form of the central bed-plate of an ordinary cooking-stove. The plate 1, is provided near its rear and front edges with openings through Which.the vertical portions of the oil-feeding inlet-pipe 2, and vapor outlet-pipe 3, pass, respectively,

l the pipes being secured to said plate and the vaporiz ing retort portion of the burner being suspended therefrom within the fire-box of the stove by means of the 1 elbow-pipe 4, and nut 5, resting upon the plate 1. The plate 1, is also provided with a mixer-opening (S, provided with a depending annular flange 7.

A horizontal oil inlet-pipe 8, is connected at one end to the elbow-pipe 4, and at its other or rear end to a needle-valve-body 9, provided at its upper end with a I screw cap or bonnet 1.0, and spindle 11. The valvebody 9, is provided-with a depending portion 12, having an inlet opening 13, and said depending portion is threaded on its exterior for connection with an oil receiving-pipe or hollow wire (not shown) communicating with any suitable and convenient source of supply.

The lower end of the vertical portion 2, of the inletpipe communicates with a horizontally-arranged elliptical gas-generating or vaporizing yoke-pipe 14, through the medium of an inverted T-pipe connection 15, carrying the rear side of the vaporizing yoke-pipe 14. The opposite or front side of the yoke-pipe 14, is connected to and carried by a second T-pipe connection 16, disposed horizontally and connected at its rear end to a retort body 17, through the medium of an opening formed in the front wall thereof and a coupling-nut 18. In this way communication is established between the retort vaporizing-chamber 17 and the branches of the horizontally-arranged vaporizing-yoke-pipe 14, communicating with the oil-inlet-pipe 8, at the rear.

The base of the retort body 17, carries an ellipticalshaped base-pan 19, and is connected thereto by means of a lug 20, and cap-screw 21.

The base-pan 19, is horizontally-arranged slightly below the plane of the vaporizing pipe 14, and is provided with a peripheral upwardly and outwardly-extending flange or rim 22, preferably within the outline flames arising from combustion under and over and about the vaporizing yoke-pipe 14, as hereinafter more fullydescribed. The pan 19, is also adapted to carry the oil or other fuel used in starting the initial fire for the preliminary heating of the yoke-pipe 14, and retort body 17, until suflicient gas has been generated; or for crude oil with the connection hereinafter described.

The top of the retort body 17, is provided with a reducing-elbow'23, the enlarged end of which is connected with a short horizontal pipe 24, connected to an elbow 25,secured to the lower end of the vertical portion 3, of the vapor outlet-pipe hereinbefore referred to.

A second elbow 26, connects the upper end of the pipe 3, with a horizontal-pipe 27, provided with a third eloi the vaporizing pipe 14, and adapted to direct the catching and carrying crude oil when it is desired to use.

how 28, carrying a vertical pipe 29, and depending nozzle orburner-tip 30, superposed directly over the mixeropening 6. i

The operation of the device is as follows: First, open needle-valve allowing oil to pass through the inlet and outlet-pipes until a little oil has been allowed to escape through the depending-nozzle-tip 30, through the mixer-opening 6, upon the base-pan 19 then close valve, light oil in pan and when generating-yoke-pipe 14, and retort 17 become hot enough, gas will escape from nozzle 30, down through mixer-opening 6, and will ignite above the base-pan depending within the fire-box oi the stove; then open valve again and regulate the flow of oil for the required amount of heat desired. -By regulating draft-dampers on stove the proper amount of gas and air are mixed in passing through mixer-opening 6. As the burning vapor or gas strikes the base-pan it is thrown outwardly over the same and flange directs the flames over and about the vaporizing yoke-pipe ]-i, and retort 1'7, thus insuring a complete vaporization of the oil. Furthermore, by reason of the construction set forth provision is made for perfect combustion for the carbon contained in the vapor fed to the flrnie; and the maximum degree of the heat units is developed and utilized to the best advantage with aminimum consumption oi oil.

it it is desired to use crude oil, the upper portions of the vapor outlet-pipe extending above the plate 1, are removed by unscrewing the lower end of the pipe 3, from the elbow 25, and a crude oil inlet-pipe like that shown in Fig. 3, is substituted and secured above the plate 1. by screwing the threaded end 31 of the solid standard 32. in the elbow 25, and the threaded end 9, of the needle-valve-body 9. is secured upon the end of l the extension inlet-pipe 33.

Having thus described my invention without having i the peripheral upwardly and outwardlyextending/ I attempted to set forth all the forms in which it may be made or all the modes of its use, I declare that what I claim and desire to secure by Letters Patent. is

1. In a burner, a vaporizing yoke-pipe an oil inlet-pipe intersecting said yoke-pipe a retort provided with a Vapor outletpipe and connected to said yokepipe by means of a Tpipe connection, and a base-pan carried by said retort parallel with and in close proximity to said vaporizing ,volrepipe and provided with a peripheral flange extending 4 toward said vaporizing yoke-pipe.

2. In a burner, the combination with a vaporizing yokepipev an intersecting oil inlet-pipe and a retort connected at its side to said yoke-pipe by means of a horizontal '1- pipe connection and provided with a vapor outlet-pipe; of a basepan carried by said retort and provided with an upwardly and outwardIy-extending peripheral flange extend ing toward said vaporizing yoke-pipe.

3 in a burner, a horizontal yoke-pipe provided with an inlebpipe and a diamet'ricallyppposite retort secured to said yol epipe by means to a Tpipe connection and provided at its top with a vapor outlet-pipe terminating in :1 depending burner-tip, a supportingplate provided with a mixer-opening below said burner-tip, and a basepan car ried by said retort below the plane of said yokepipe and provided with an upwardly and outwardly-extending pe ripheral flange adapted to direct the flame against said yoke-pipe.

i. A burner, comprising a supporting-plate provided with a mixer-opening and an oil inlet-pipe, a vapor outletpipe intersecting said supporting-plate and terminating in :1 depending nozzle above said opening, a vaporizing yokepipe connected to said inletpipe by means of an inverted T-pipe connection. a retort provided at its side, opposite said T-pipe connection, with a horizontal T-pipe connection secured to said yoke-pipe and secured at its top to said outlet-pipe, and a horizontal base-pan carried by said retort below the plane of said yoke-pipe and provided with a peripheral flange extending toward said 'y0ke-pipe.

in testimony whereof I have signed my name to this specification in the presence'ot two subscribing witnesses.
